Sony Ericsson has relaunched their long awaited first entry into Windows Mobile devices for the US with the Sony Ericsson X1a after a Black Friday launch met with lower than expected stock numbers, and disappointed potential customers with the device quickly selling out.

As PhoneNews.com reported previously, the X1a does not support the W-CDMA 1700 frequency used by T-Mobile USA and instead features US 3G HSPA support on the 850/1900 bands as well as HSPA 2100 for international roaming. Â The device also features Internet Explorer Mobile and Opera Mobile 9.5.

The device is now available directly from SonyStyle for $799.99 unlocked with a shpping date of tomorrow listed, marking more ample supply.
